STALIN [3.7K]

The correct statements are 1, 2, and 5 as they explain the adaptations that mussels developed to prevent their extinction and how this aided them in natural selection.

Crabs are omnivores. The smaller crabs can eat seaweed, worms, shrimp, algae, etc while the larger ones can eat mussels, snails, and squid. Crabs can change their feeding grounds because of environmental changes. Mussels being the prey of crabs were forced the development of new traits to ensure their survival. They started to produce thicker shells. This allowed the mussels with thicker shells to survive as they would not get eaten by the crabs, thus undergoing natural selection. The development of said trait improved the survival rate of mussels and prevented them from going extinct due to predation.

Note: The question seems to be incomplete and the options could have been

  1. "A change in the environment led to a new distribution of traits in a population.
  2. The trait of shell thickening underwent natural selection.
  3. The trait for shell thickening will not be selected by future mussel generations.
  4. Half of the mussel population developed the trait while the other half did not.
  5. Mussels with the shell thickening trait had a greater chance of survival."

Which one of the following discoveries involving DNA happened first?
EastWind [94]
<span>A. Hershey and Chase used bacteriophages to confirm that DNA was the genetic material in genes.

</span>According to the central dogma of molecular biology,  the process of protein synthesis in living organisms follows the  order: DNA →RNA→ Protein.Information for synthesis of a particular protein is copied (transcribed) from DNA onto mRNA in a process called transcription, in the cell nucleus.<span>mRNA (messenger RNA) leaves the cell nucleus and enters the cytoplasm where it attaches to a ribosome.  tRNA (transfer RNA)  begins to decode (translate) the information on the attached mRNA in a process called translation and fetches amino acids corresponding to this information from the pool of free amino acids in the cytoplasm, and brings them to the ribosome where they are joined together into a chain and thus the protein is formed.</span>

After the ovules are fertilized what happens to the ovary
3241004551 [841]

Answer:ovary develops into fruits

Explanation: fertilization occur after the fusion of a haploid male and female gametes to give a diploid zygote. The male sperm fuses with the female egg in the ovule to give an embryo. For angiosperms the male sex cell is located in the pollen in the anther which is carried to the stigma where the female sex cell is located either of the same plant or different plant. For gymnosperms the male pollen is found in the cone from where it is then transfer to the female cone. The ovule developed into the seeds after fertilization and the ovary develops into fruits.
